Kirill Tkhai c6fae49a44 kcm: Fix use-after-free caused by clonned sockets
[ Upstream commit eb7f54b90b ]

(resend for properly queueing in patchwork)

kcm_clone() creates kernel socket, which does not take net counter.
Thus, the net may die before the socket is completely destructed,
i.e. kcm_exit_net() is executed before kcm_done().
